Theme Options (like Wordpress)

The advantage to this feature is that I can change the logo, colors, slideshows, etc from the theme options. This was they aren't packaged with the theme itself.

The advantage of this is that I can have 50 sites running from the same theme, and if i need to make the change to the css, then I only need to make it in one set of code (I don't need to have a copy for each of my clients with specific branding).

I am just wondering whether this is possible with Orchard, or whether the branding needs to go into the theme that I have created. Thanks!
